How to Create a WiFi QR Code - Step by Step

1
Open QRCrack and select the WiFi QR tool from the tools menu.
2
Enter your network name (SSID) exactly as it appears in your device's WiFi settings - capitalization matters.
3
Enter your WiFi password. Choose WPA/WPA2 for most modern routers, WEP for older hardware, or None for open networks.
4
Click generate. The QR encodes instantly in your browser - nothing is sent to any server.
5
Download as PNG for printing on a sign, or SVG for large-format displays without quality loss.
6
Print and place near the entrance, on tables, or on a welcome card. Guests scan once and stay connected.

Where to Use WiFi QR Code Codes

+
Cafes and restaurants - guests connect without asking staff for the password every few minutes.
+
Airbnb and short-term rentals - print a welcome card with the QR and guests connect the moment they arrive.
+
Conference rooms and coworking spaces - one QR per room, updated by reprinting when credentials change.
+
Retail stores - connect shoppers for loyalty app access or in-store browsing.
+
Home networks - put a small framed QR near your router so visitors self-serve.
+
Events and pop-ups - tape the QR to a registration table so attendees can connect as they check in.

Frequently Asked Questions

Does the WiFi QR code store my password on QRCrack's servers?

No. QRCrack generates QR codes entirely in the browser using JavaScript. Your network name and password never leave your device - they are encoded locally into the QR image before download.

Which security type should I choose?

WPA/WPA2 covers virtually all home and office routers sold since 2004. Choose WEP only if your router firmware is too old to support WPA - WEP has known vulnerabilities and should be updated. Choose None only for intentionally open guest networks.

Can someone extract my password from the QR code?

Yes - any QR scanner app can decode the raw text and reveal the password. The QR format is not encrypted. For high-security networks, create a separate guest network with a throwaway password before generating the QR.

Does it work on iPhones without a QR reader app?

Yes. iOS 11 and later detect QR codes natively in the Camera app. Point the camera at the code, tap the notification banner, and iOS prompts to join the network - no third-party app needed.
